INHA'LER AND EXHALER.

Patented Feb. 27, 1906.

Application filed June 27, 1904. Serial No. 214,304.

To all whom it may concern:

Be it known that I, JOHN LAWRENCE HILL, a citizen of the United States,residing at the city of Jackson, in the county of Jackson and State ofMichigan, have invented certain new and useful Improvements in Inhalersand Exhalers, of which the following is a specification.

This invention relates to improvements in inhalers and eXhalers.

The main object of this invention is to provide an improved inhaler andeXhaler which is simple and economical in structure and convenient touse.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention.

by the devices and means described in the following specification.

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which Figure 1 is an elevation view of my improvedinhaler and eXhaler. Fig. 2 is a longitudinal sectional view thereof,taken online 2 2 of Fig. 1. Fig. 3 is a cross-sectional view taken on aline corresponding to line 3 3 of Fi 2.

In the drawings the sectional views are taken looking in the directionof the little arrows at the ends of the section-lines, and similarletters of reference refer to similar parts throughout the severalviews.

Referring to the drawings, the inhaler member A and the eXhaler member Aare tubular or hollow and are internally screwthreaded at their innerends. A threaded coupling A is provided. This coupling also seals theinner ends of the two members. The two portions are preferably ofuniform size, so that when secured together they present a uniformappearance. The inhaler member is provided with a nasal tip at its outerend and the exhaler member is provided witha mouthpiece or tip at itsouter end.

The inhaler A is provided with transversely-opening inlet-ports a at itsinner end, and the eXhaler portion A is provided with atransversely-opening reticulated deliveryport a. at its inner end. Thechamber in the inhaler member A is filled with a suitable material B,such as absorbent cotton, adapted to absorb a medicament, so that theair inhaled therethrough is suitably medicated. A removable perforateddisk-like partition B is provided to retain the medicated material inplace. This partition-plate is arranged within the ports, so that italso prevents the clogging of the same.

In inhaling, the nasal tip is used and the air passing through themedicated material B is suitably medicated. The air is also freed fromany dust or the like. The mouthpiece or tip is then placed in the mouthand the air exhaled therethrough. As the delivery-port a is ofcomparatively small dimension, considerable force is required inexpelling the air. This brings the muscles of the lungs into action, andthemedicated air is forced through the lung-cells, opening andexercising the same and at the same time carrying the medicamenttherethrough.

My improved inhaler and eXhaler is very compact in structure andconvenient to use. It is also attractive in appearance and possesses thefurther advantages of being economical to produce and durable in use.

I have illustrated and described my improved inhaler and exhaler indetail in the form preferred by me on account of its structuralsimplicity and economy, although I am aware that it is capable ofconsiderable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a device of the class described, the combination of a hollowinhaler member having inlet-ports in the walls thereof and internalscrew-threads; a hollow eXhaler member having a restricted delivery-portand internal screw-threads; a threaded coupling for said members adaptedto seal their inner ends a filling for said inhaler member adapted toreceive a medicament; and a removable perforated partition for saidinhaler member, for the purpose specified.

2. In a device of the class described, the combination of a hollowinhaler member having inlet-ports in the walls thereof and internalscrew-threads; a hollow eXhaler member having a restricted delivery-portand interhaler member having a mouthpiece at its outer end and arestricted delivery-port; and a coupling for the inner ends of saidmembers, for the purpose specified.

4:. In a device of the class described, the

combination of an inhaler member having a nasal tip at its outer end andinlet-ports at its inner end, and a receptacle for medicament; anexhaler member having a mouthpiece at its outer end and a restricteddeliverypot; and a coupling for the inner end of said members, for thepurpose specified.

In Witness whereof I have hereunto set my hand and seal in the presenceof two Witnesses.
